Description

Technical Field

[0001] This utility model relates to the field of humidifiers, and in particular to an air conditioner humidifier. Background Technology

[0002] The storage of medicines in pharmaceutical warehouses, the preservation of paper documents in archives and libraries, the preservation of cultural relics in museums, the computer rooms of data centers and servers, and the cultivation of agricultural greenhouses all have high requirements for environmental temperature and humidity. Therefore, existing technologies often combine humidifiers with air conditioning systems. One common method is to send water mist into the air conditioner's evaporator. However, a large number of mist droplets condense into liquid water as they pass through the evaporator, and more than 60% of the water is ultimately discharged from the unit. This not only causes serious water waste but may also lead to the risk of unit leaks. Although humidification solutions with condensate recovery already exist, such as the air conditioner humidifier disclosed in invention patent CN105928120A, which includes a humidifier body, an atomizer at the bottom of the humidifier body, and a mist outlet on one side wall of the humidifier body, the mist outlet communicating with a mist outlet cavity located outside the side wall of the humidifier body, and a mist outlet pipe fixedly connected to the outer wall of the mist outlet cavity that can extend laterally into the air conditioner outlet, with the mist outlet pipe inclined upwards, the inclination angle of the mist outlet pipe in this technical solution is a single fixed slope. If the entire mist outlet pipe... If the tilt angle is too small, meaning the slope of the mist outlet pipe is too gentle, the condensate will flow back slowly due to insufficient gravity. Especially when the pipe is long, water droplets tend to stagnate in the middle and later sections, forming a continuous water film. This not only increases airflow resistance but may also be re-entrained into the airflow when the fan starts or stops or when the airflow fluctuates, resulting in water in the mist. If the slope of the entire mist outlet pipe is too large, meaning the mist outlet pipe is too steep, the mist needs to overcome a greater gravity to flow upward, which can easily cause airflow disturbance and droplet impact on the pipe wall, resulting in decreased atomization efficiency, increased energy consumption, and possible noise. Utility Model Content

[0003] The purpose of this invention is to provide an air conditioning humidifier that solves the problem in the prior art of simultaneously meeting the dual requirements of effective condensate return and smooth airflow, enabling the mist outlet pipe to promote the return of condensate to the humidifier while ensuring efficient mist delivery.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an air conditioning humidifier, comprising a body having an atomizing chamber, the atomizing chamber being equipped with an atomizer, the body being provided with an air inlet and a mist outlet communicating with the atomizing chamber, the air inlet being equipped with a fan, the mist outlet being connected to a mist outlet pipe, the mist outlet pipe sequentially comprising a first inclined pipe section and a second inclined pipe section, the first inclined pipe section being inclined upward from the mist outlet, the second inclined pipe section being inclined upward from the first inclined pipe section and used to communicate with the external environment, the slope of the first inclined pipe section being greater than the slope of the second inclined pipe section.

[0005] After adopting the above technical solution, this utility model has the following advantages: The temperature difference near the mist outlet is large, the mist temperature is high, and the flow velocity is fast, easily generating a large amount of condensate. Setting a first inclined pipe section with a large slope can fully utilize gravity, significantly reducing the resistance to condensate return flow, achieving rapid and smooth return to the atomizing chamber, effectively reducing the risk of water accumulation, and allowing the condensate to be circulated and atomized for reuse. The mist, just exiting the atomizing chamber, has high kinetic energy and flow velocity, possessing strong directionality and inertia. Its own kinetic energy is sufficient to overcome the gravitational component brought about by the large slope, therefore its impact on the overall airflow resistance is relatively small. As the mist flows downstream, the temperature gradually approaches the ambient temperature, the amount of condensate decreases, and the airflow kinetic energy is attenuated due to friction and diffusion. At this point, using a second inclined pipe section with a smaller slope, while meeting the basic return requirement of residual condensate, slows down the upward trend of the pipe, reducing the resistance to continuous airflow rise. To minimize excessive energy loss and ensure a stable delivery of mist to the environment for humidification, the first and second inclined pipe sections effectively reduce condensate discharged with the airflow, preventing moisture and water mist from entering the air conditioning duct system. This minimizes condensate accumulation inside the air conditioning unit, reducing risks such as pollution, mold growth, and corrosion of metal components. It extends the lifespan of the air conditioning unit and humidifier, reduces failure rates and maintenance frequency due to water accumulation, and significantly lowers subsequent maintenance costs. Most importantly, this solution efficiently recovers and recycles condensate, significantly reducing water waste caused by condensate drainage in traditional humidification methods. This achieves closed-loop water resource utilization, greatly improving water efficiency in the humidification process and demonstrating outstanding water-saving benefits. Thus, it achieves comprehensive optimization of efficient humidification, reliable condensate recovery, and long-term stable operation of the humidification system.

[0006] Furthermore, an arc-shaped transition section is provided between the first inclined pipe section and the second inclined pipe section of the mist outlet pipe.

[0007] Using the aforementioned technical solution, the arc-shaped transition section connects the first inclined pipe section and the second inclined pipe section, which avoids sharp bends in the mist outlet pipe at the slope change point as much as possible, effectively reducing eddies and disturbances in the mist flow process, reducing airflow resistance, and preventing mist droplets from condensing or splashing back when they hit the pipe wall. At the same time, the arc-shaped transition section allows the condensate to flow continuously and smoothly during the return process, reducing the accumulation or blockage of condensate at the corners, and further improving the smoothness of condensate return.

[0008] Furthermore, the second inclined section of the mist outlet pipe is inclined upward at a slope of 4% to 10%.

[0009] Using the aforementioned technical solution, the second inclined pipe section slopes upwards at a gradient of 4% to 10%. This moderate gradient provides sufficient angle for residual condensate to continuously flow back under gravity, minimizing liquid accumulation, while avoiding excessive elevation of the mist outlet pipe, effectively controlling installation space requirements. Furthermore, this slope range better matches the airflow direction, minimizing impact on mist delivery resistance and promoting stable mist output. If the slope of the second inclined pipe section is less than 4%, the angle is too gentle, resulting in insufficient driving force for condensate to flow back along the pipe wall, especially in… When the pipe is long or the ambient temperature is low, water droplets are prone to stagnation and coalesce into a film, making it difficult to return to the atomization chamber. This can easily cause water accumulation and leakage, or even be carried out by the airflow when the fan starts or stops, resulting in water in the mist and affecting the humidification effect and system safety. If the slope is greater than 10%, the mist outlet pipe rises too steeply, significantly increasing the vertical installation height, occupying too much space, and making it difficult to arrange the equipment compactly. At the same time, it creates a large lifting resistance for the mist, increases the fan load, and may cause airflow disturbance and mist droplet collision with the pipe wall, reducing the delivery efficiency and potentially causing noise and increased energy consumption.

[0010] Furthermore, the second inclined section of the mist outlet pipe is inclined upward at a constant slope in a direction away from the first inclined section; or, the slope of the second inclined section of the mist outlet pipe gradually increases in a direction away from the first inclined section.

[0011] Using the aforementioned technical solution, the second inclined pipe section adopts a constant slope and a regular structure, which facilitates processing, manufacturing, installation, and positioning. This is conducive to smooth airflow and reduces eddies and resistance caused by sudden changes in pipe diameter or slope. At the same time, while meeting the minimum return slope, it ensures that condensate flows back continuously and evenly along the pipe wall as much as possible, avoiding local water accumulation and achieving stable and reliable drainage and misting performance. Alternatively, the slope of the second inclined pipe section gradually increases along the airflow direction, making the slope smaller near the front end to reduce the airflow resistance in the initial section and facilitate the smooth entry of mist. The slope increases further towards the end, enhancing the driving force for the return of residual condensate, so that condensate can still effectively return at the end of the pipe.

[0012] Furthermore, the first inclined pipe section is vertically arranged.

[0013] Through the above technical solution, the first inclined pipe section is set vertically, so that the condensate near the mist outlet falls vertically and quickly under the action of gravity. The return path is the shortest and the resistance is the least, which significantly improves the return efficiency of a large amount of condensate in the early stage and minimizes water accumulation. At the same time, the vertical structure has minimal impact on the flow direction of high-velocity mist. The airflow is straight along the axial direction, which avoids additional resistance and disturbance caused by the tilt and lifting as much as possible. This is conducive to maintaining the kinetic energy of the mist and smoothly entering the subsequent pipe section, achieving synergistic optimization of efficient transportation and reliable drainage.

[0014] Furthermore, the inner wall of the mist outlet pipe is provided with a hydrophobic coating.

[0015] Through the above technical solution, the inner wall of the mist outlet pipe is equipped with a hydrophobic coating, which can significantly reduce the adhesion of water molecules to the pipe wall, making it difficult for condensed water to spread into a film. Instead, it gathers into water droplets and then quickly slides back into the atomization chamber under the action of gravity, reducing bacterial growth and contamination inside the pipe, and improving the hygiene and operational reliability of the equipment.

[0016] Furthermore, the first inclined pipe section is a flexible pipe.

[0017] Through the above technical solution, the first inclined pipe section adopts a flexible pipe, which can flexibly adjust the bending shape and inclination angle of the pipe according to the actual installation requirements, so as to ensure that a reasonable condensate return path can be achieved under different installation conditions, while taking into account the stability of airflow delivery, improving the product's adaptability to diverse application scenarios, and enhancing the convenience and reliability of use.

[0018] Furthermore, the second inclined pipe segment and the first inclined pipe segment are detachably connected; or, the second inclined pipe segment includes at least two detachably connected pipe sections.

[0019] Through the above technical solutions, the first inclined pipe section and the second inclined pipe section can be detachably connected, which facilitates segmented assembly during installation or maintenance, adapts to space-constrained occasions, and allows for disassembly and cleaning of areas where condensate easily accumulates in the mist outlet pipe, improving maintenance convenience and reducing bacterial growth; or, the second inclined pipe section is designed to consist of at least two detachably connected pipe sections, which facilitates segmented disassembly during maintenance, allowing cleaning tools to penetrate deep into the pipe and effectively remove condensate residue and dirt that are difficult to reach in long pipe sections. It also allows for flexible adjustment of the total length of the mist outlet pipe according to the actual connection distance, minimizing installation difficulties caused by pipes that are too long or too short.

[0020] Furthermore, the mist outlet is located at the top of the atomizing chamber.

[0021] With the above technical solution, the mist outlet is located at the top of the atomizing chamber, allowing the mist outlet pipe to extend from the top and naturally connect with the vertical or upward-sloping pipe section. This facilitates the alignment of the mist outlet direction with the airflow direction, reducing flow resistance. Simultaneously, condensate naturally flows back down the pipe wall into the atomizing chamber under gravity, minimizing accumulation near the mist outlet and ensuring a smooth return path. Furthermore, this layout minimizes the risk of liquid backflow into the mist outlet pipe when the liquid level in the atomizing chamber rises.

[0022] Furthermore, both the air inlet and the mist outlet are located on the same side of the atomizing chamber facing the liquid surface of the atomizing chamber.

[0023] The above technical solution allows external airflow to enter through the air inlet and directly blow the mist generated by the atomizer, pushing it along a set path to the mist outlet on the same side, forming a highly efficient and directional airflow effect, improving the efficiency of mist capture and delivery, and also facilitating the integration of the fan and the mist outlet pipe on the same side, improving installation convenience and overall compactness, especially suitable for miniaturized and modular humidification equipment.

[0035] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0036] like Figures 1 to 4 As shown, this utility model provides an air conditioner humidifier, including a body 10 with an atomizing chamber 11, an atomizer 12 in the atomizing chamber 11, an air inlet 13 and a mist outlet 15 communicating with the atomizing chamber 11, a fan 14 at the air inlet 13, and a mist outlet 16 connected to the mist outlet 15. The mist outlet 16 includes a first inclined pipe section 161 and a second inclined pipe section 162. The first inclined pipe section 161 is inclined upward from the mist outlet 15, and the second inclined pipe section 162 is inclined upward from the first inclined pipe section 161 and is used to communicate with the external environment. The slope of the first inclined pipe section 161 is greater than the slope of the second inclined pipe section 162.

[0037] Due to the large temperature difference, high mist temperature, and high flow velocity near the mist outlet 15, a large amount of condensate is easily generated. The first inclined pipe section 161 with a larger slope fully utilizes gravity, significantly reducing the resistance to condensate return flow and achieving rapid and smooth return to the atomizing chamber 11. This effectively reduces the risk of water accumulation and allows the condensate to be recycled and reused, reducing water waste. When the mist first exits the atomizing chamber 11, it has high kinetic energy and flow velocity, possessing strong directionality and inertia. Its own kinetic energy is sufficient to overcome the gravitational component caused by the large slope, thus having a relatively small impact on the overall airflow resistance. As the mist flows downstream, the temperature gradually approaches the ambient temperature, and the amount of condensate decreases. Simultaneously, the airflow energy decreases due to friction and diffusion. At this point, the second inclined pipe section 162 with a smaller slope is used. While meeting the basic return requirement of residual condensate, it slows down the upward trend of the pipe, reducing the resistance to continuous airflow rise. This approach can avoid excessive energy loss and ensure a stable delivery of mist to the environment for humidification. The first inclined pipe section 161 and the second inclined pipe section 162 can effectively reduce the condensate discharged with the airflow, and minimize the entry of moisture and water mist into the air conditioning duct system. This minimizes the accumulation of condensate inside the air conditioning unit, reducing the risks of pollution, mold growth, and corrosion of metal components. It also ensures the service life of the air conditioning unit and humidifier, reduces the failure rate and maintenance frequency caused by water accumulation, and significantly reduces the later maintenance costs of the equipment. More importantly, this solution significantly reduces the water waste caused by condensate drainage in traditional humidification methods by efficiently recovering and recycling condensate, realizing closed-loop utilization of water resources and greatly improving the water efficiency of the humidification process. It has outstanding water-saving benefits, thus achieving comprehensive optimization of efficient humidification, reliable condensate recovery, and long-term stable operation of the humidification system.

[0038] It should be noted that, in one embodiment, the air inlet 13 is connected to the external environment through an air inlet channel 22, and the fan 14 is disposed within the air inlet channel 22. Air is driven by the fan 14 and enters the atomizing chamber 11 through the air inlet channel 22 and the air inlet 13. The air inlet channel 22 can guide the airflow, reduce flow resistance, and improve air intake efficiency. In another embodiment, the air inlet is directly connected to the external environment, and the fan is located within the air inlet. Air is driven by the fan and sent into the atomizing chamber from the air inlet. This structure simplifies the air duct design and helps to reduce the size of the equipment.

[0039] It should be noted that the atomizer 12 includes an ultrasonic atomizing plate, which can be configured with one or more plates to adjust the atomization volume according to humidification needs. The fan 14 is driven by a low-power, high-efficiency motor, such as a DC motor with a rated power of 15W. It can provide stable and continuous airflow power with low energy consumption. In particular, compared with the existing technology that uses a large 1.1KW fan built into the air conditioner for humidification, the energy-saving effect is more significant. Moreover, when using a large fan for humidification, the airflow of the ultrasonic humidifier will be too large. The high-speed airflow will cause the newly generated tiny mist droplets to collide violently and coalesce, forming larger water droplets. These water droplets cannot be effectively suspended and diffused. They will not only be sprayed out from the mist outlet 15 and drip onto goods or air conditioning equipment, causing pollution, corrosion, or water accumulation, but also reduce the actual mist output, significantly reduce humidification efficiency, and affect the use effect. The main body 10 is equipped with a water inlet 18 and a water outlet 19. The humidifier uses purified water as its water source, which is added to the atomizing chamber 11 through the water inlet 18. Under the high-frequency vibration of the ultrasonic atomizing plate, the purified water is broken into extremely fine mist particles with a particle size of 1 to 5 micrometers. These tiny mist particles are rapidly diffused by the airflow introduced by the fan 14 and transported to the external environment through the mist outlet pipe 16, achieving a highly efficient and clean humidification effect.

[0040] It should be noted that the embodiment shown in the figure integrates the air conditioning humidifier and the air conditioning unit of this application into the same housing 1, forming an integrated structure. The housing 1 has an air outlet 21 for the air conditioner, located on one side of the mist outlet pipe 16, facilitating the simultaneous mixing and delivery of the air and humidified airflow. The second inclined section 162 of the mist outlet pipe 16 has multiple mist outlet holes 164 distributed along its length, which can evenly spray the atomized fine water mist into the airflow channel, achieving efficient mixing with the air conditioning airflow, improving humidification uniformity and response speed. This integrated design is compact, saves space, and is conducive to airflow organization optimization and overall unit coordinated control, making it suitable for environments with high requirements for installation space and airflow quality.

[0041] It should be noted that the first inclined pipe section 161 is close to the mist outlet 15, where the mist has just been ejected from the atomizing chamber 11, resulting in high velocity, high density, and a large amount of condensate. If a mist outlet 164 were installed in this section, condensate could easily drip from the outlet or be carried out by the airflow, causing risks such as water accumulation inside the air conditioner or corrosion of metal components, thus affecting the service life of the air conditioning unit humidifier. Therefore, the first inclined pipe section 161 does not have a mist outlet 164, which is beneficial for concentrating and guiding the initial mist, maintaining stable airflow, and ensuring smooth condensate return as much as possible.

[0042] If the slope of the second inclined pipe section 162 is less than 4%, the inclination angle is too gentle, and the driving force for the return flow of condensate along the pipe wall is insufficient. Especially when the pipe is long or the ambient temperature is low, water droplets are prone to stagnation and coalesce into a film, making it difficult to return to the atomization chamber 11. This can easily cause water accumulation and leakage, or even be carried out by the airflow when the fan 14 starts and stops, resulting in water in the mist, affecting the humidification effect and system safety. If the slope is greater than 10%, the mist outlet pipe 16 rises too steeply, significantly increasing the vertical installation height, occupying too much space, which is not conducive to the compact layout of the equipment. At the same time, it creates a large lifting resistance for the mist, increases the load on the fan 14, and may cause airflow disturbance and mist droplet collision with the pipe wall, reducing the delivery efficiency, and may also cause noise and energy consumption to increase. Therefore, in this application, the second inclined section 162 of the mist outlet pipe 16 is inclined upwards at a slope of 4% to 10%, corresponding to an inclination angle of approximately 2.3° to 5.7°, which is an increase of 4 cm to 10 cm per meter of length. This moderate slope provides sufficient inclination angle to allow residual condensate to continuously flow back under gravity, minimizing liquid accumulation, while avoiding excessively raising the height of the mist outlet pipe 16, effectively controlling installation space requirements. Furthermore, this slope range better matches the airflow direction, minimizing the impact on mist delivery resistance and contributing to stable mist output.

[0043] Preferably, the second inclined section 162 of the mist outlet pipe 16 is inclined upwards at a slope of 4%, i.e., the inclination angle is approximately 2.3°, which is equivalent to an increase of 4 centimeters per meter of length of the second inclined section 162. The first inclined section 161 is vertically arranged. This structural design fully considers the dual requirements of condensate return and mist delivery: near the mist outlet 15, due to the high temperature and high moisture content of the mist, there is a significant temperature difference, which easily generates a lot of condensate. The vertically arranged first inclined section 161 allows the condensate to fall rapidly in the vertical direction under the action of gravity, with the shortest return path and the least resistance, significantly improving the initial condensate recovery efficiency and minimizing the risk of water accumulation; at the same time, the airflow in this section has just been ejected from the atomizing chamber 11, with greater kinetic energy and higher flow velocity. The vertical channel has the least impact on the airflow direction, achieving smooth axial conduction and minimizing the additional resistance and disturbance caused by the inclined lifting, which is conducive to maintaining the smooth transition of mist kinetic energy to subsequent pipe sections. The second inclined pipe section 162 adopts a 4% gentle slope design. While meeting the return flow requirements of reduced condensate volume, it further reduces the overall rise height of the pipe, minimizing the burden of continuous airflow lifting, and balancing installation space constraints with delivery efficiency. These two factors work together to achieve synergistic optimization of efficient condensate return and stable mist output.

[0044] Furthermore, the second inclined section 162 of the mist outlet pipe 16 is inclined upwards at a constant slope in a direction away from the first inclined section 161. This design has a regular structure, facilitates processing, manufacturing, and installation, and is conducive to stable mist delivery. The constant slope minimizes eddies and additional airflow resistance caused by sudden slope changes in the pipeline, improving the smoothness of mist output. At the same time, under the condition of meeting the minimum slope required for condensate return, it can ensure that condensate returns continuously and evenly along the pipe wall as much as possible, preventing local water accumulation as much as possible, thereby achieving a balance between drainage reliability and mist output stability.

[0045] Because the slope difference between the first inclined pipe section 161 and the second inclined pipe section 162 is significant, their direct connection easily creates a sharp angle at the slope change point, causing eddies and disturbances during mist flow, increasing airflow resistance. Simultaneously, mist droplets are prone to impacting the pipe wall and condensing or splashing back, affecting mist output efficiency. Therefore, this application provides an arc-shaped transition section 163 between the first inclined pipe section 161 and the second inclined pipe section 162, making the pipe slope change smooth and continuous, effectively reducing airflow disturbance and resistance, and improving the stability of mist delivery. At the same time, the arc-shaped structure facilitates continuous and smooth backflow of condensate along the pipe wall, avoiding accumulation or blockage at corners, further improving drainage reliability.

[0046] To facilitate adjustment of the slope of the mist outlet pipe 16, in this application, the first inclined pipe section 161 and the arc-shaped transition section 163 are flexible pipes, such as corrugated pipes. The bending shape and inclination angle of the pipes can be flexibly adjusted according to actual installation requirements, allowing the slope of the first inclined pipe section 161 and the arc-shaped transition section 163 to be set as needed. This ensures a reasonable condensate return path under different installation conditions while also considering the stability of airflow, improving the product's adaptability to diverse application scenarios and enhancing its ease of use and reliability. Since the second inclined pipe section 162 is relatively long, a flexible pipe would be prone to deformation and water accumulation. Therefore, the second inclined pipe section 162 is a rigid pipe.

[0047] To further reduce the accumulation of condensate in the mist outlet pipe 16, a hydrophobic coating is provided on the inner wall of the mist outlet pipe 16. This coating can significantly reduce the adhesion of water molecules to the pipe wall, making it difficult for condensate to spread into a film. Instead, the condensate gathers into water droplets and then quickly slides back into the atomizing chamber 11 under the action of gravity, reducing bacterial growth and contamination inside the pipe, and improving the hygiene and operational reliability of the equipment.

[0048] It should be noted that the hydrophobic coating can be one of polytetrafluoroethylene, fluorinated ethylene propylene copolymer, silica-based superhydrophobic coating, or fluorinated silane materials. These materials have good hydrophobic properties, and the contact angle of the hydrophobic coating is usually greater than 120°, which can effectively reduce the adhesion of water to the wall of the mist outlet tube 16, allowing condensate to quickly flow back to the atomizing chamber 11 in the form of water droplets, reducing the risk of liquid accumulation and microbial growth, and improving the self-cleaning ability and operational reliability of the mist outlet tube 16.

[0049] Because the mist outlet pipe 16 is typically quite long, its overall structure is difficult to install and clean, especially in situations where space is limited or condensate easily accumulates inside the pipe, leading to problems such as inconvenient installation, difficult cleaning, and easy bacterial growth. Therefore, this application sets the second inclined pipe section 162 and the first inclined pipe section 161 as a detachable connection. This not only facilitates segmented assembly during installation, adapting to different spatial layouts and installation conditions and improving assembly flexibility, but also allows for disassembly and cleaning during maintenance. This enables cleaning tools to penetrate deep into the interior of the mist outlet pipe 16, effectively removing condensate residue and dirt, minimizing cleaning blind spots, significantly improving cleaning thoroughness and hygiene performance, while reducing the risk of blockage, odor, and microbial growth caused by water accumulation during long-term use, thus improving the convenience of equipment maintenance and operational reliability.

[0050] In this embodiment, the mist outlet 15 is located at the top of the atomizing chamber 11. This allows the mist outlet pipe 16 to extend from the top, naturally connecting with a vertical or upwardly inclined pipe section. This facilitates the alignment of the mist outlet direction with the airflow direction, reducing flow resistance. Simultaneously, condensate naturally flows back down the pipe wall to the atomizing chamber 11 under gravity, minimizing accumulation near the mist outlet 15 and ensuring a smooth return path. Furthermore, this arrangement minimizes the risk of liquid backflow into the mist outlet pipe 16 when the liquid level in the atomizing chamber 11 rises.

[0051] Furthermore, the mist outlet 15 is located on the side of the atomizing chamber 11 facing the liquid surface, and the air inlet 13 and the mist outlet 15 are located on the same side of the atomizing chamber 11. This allows the external airflow to enter through the air inlet 13 and directly blow the mist generated by the atomizer 12, pushing it to flow along a set path to the mist outlet 15 on the same side, forming a highly efficient and directional airflow effect, improving the efficiency of mist capture and delivery, and also facilitating the integration of the fan 14 and the mist outlet pipe 16 on the same side, improving installation convenience and overall compactness, especially suitable for miniaturized and modular humidification equipment.

[0052] It should be noted that the main body 10 is equipped with an overflow port 20, and the atomizing chamber 11 is equipped with a liquid level sensor 17, which is used to monitor the water level in the atomizing chamber 11 in real time and realize automatic control. When the water level is lower than the set lower limit, the system automatically starts the water replenishment device to replenish water, so as to avoid the atomizer 12 from operating in a waterless or low water state and to prevent dry burning damage as much as possible. During the water replenishment process, the liquid level sensor 17 continuously monitors the water level change. When the water level reaches the set upper limit, it promptly sends a signal to cut off the water replenishment and stop the water intake. The overflow port 20 is set at the upper limit water level as a safety redundancy, which can discharge excess water in case of control abnormality, and prevent the water level from being too high, causing liquid to overflow or backflow into the air inlet 13 and the mist outlet 15, which may cause short circuit, water carried by the airflow, and other risks.

[0053] Understandably, in other embodiments, the first inclined pipe section and the arc transition section can also be made of heat-insulating and moisture-proof flexible materials, such as flame-retardant and corrosion-resistant PVC expansion pipes with insulation layers. This can effectively reduce heat loss and condensation during the transportation process of mist, reduce condensation loss, and utilize the flexible structure to adapt to different installation requirements, making it easy to adjust the pipe direction and slope, and improve the system's sealing performance and ease of use.

[0054] Understandably, in other embodiments, the slope of the second inclined section of the mist outlet pipe gradually increases in the direction away from the first inclined section, so that the slope is smaller near the front end, reducing the airflow resistance in the initial section and facilitating the smooth entry of mist. The slope increases further back, enhancing the driving force for the return of residual condensate, so that the condensate can still effectively return at the end of the pipe.

[0055] Understandably, in other embodiments, the mist outlet pipe is a rigid pipe, for example, made of rigid plastic or metal. The rigid pipe structure has good dimensional stability and mechanical strength, and is not easily deformed or sagging after installation. It can maintain the preset slope of the first and second inclined pipe sections for a long time, ensuring that the condensate return path is always unobstructed, thereby minimizing problems such as water accumulation or poor return flow caused by pipe deformation. At the same time, the rigid pipe has better sealing performance and more reliable connections, making it particularly suitable for vibration environments or occasions requiring high long-term operational stability, thus improving the overall reliability and durability of the humidifier.

[0056] It is understood that in other embodiments, the second inclined pipe section includes at least two detachably connected pipe sections, for example, divided into two or more sections. This is particularly suitable for scenarios with long mist outlet pipes, facilitating segmented disassembly during maintenance. This allows cleaning tools to penetrate deep into the interior of the mist outlet pipe, effectively removing hard-to-reach condensate residue and scale buildup in long pipe sections, minimizing cleaning blind spots, and significantly improving cleaning thoroughness and equipment hygiene. Simultaneously, the connection length of each pipe section can be flexibly adjusted according to actual installation needs, adapting to different equipment spacing, minimizing installation difficulties caused by excessive bending due to an excessively long mist outlet pipe or inability to connect due to an excessively short pipe, thus improving the product's adaptability and installation convenience in diverse application environments.

[0057] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
